PLATINUM RESISTANCE DETECTORS (RTD)

Standard Configuration:

1) 4-wire (4-wire is easily adapted to 2-wire or 3-wire)

2) European (E): infinity = 0.00385

3) Resistance:100 Ohms

4) ± 0.1 º C tolerance

5) Sheaths 1/8 or 1/4 inch ( 3.175 or 6.350 mm) O. D. is standard

Minimum practical length: two (2) inches ( 50.8 mm )

Part number composition: Example: 4E164-11-X-Y-RB

4 (4-wire) + E (European) + 16 (#16 alloy) + 4 (1/4" O. D.) + 1 (100 Ohms)

+ 1 (± 0.1 º C tolerance) + X ( Overall length of RTD) + Y (length of Probe)

+ RB (mounting, Reverse Bushing)

For Dual Element insert "D" after the first letter in the part number.
Example: 4ED164-11-X-Y

TECHNICAL INFORMATION:

Platinum Resistance Detectors (RTDs) are more accurate with less drift over narrow
ranges than thermocouples but are not as durable. They respond slower, and they
are more expensive. Construction of a complete assembly may be similar to a
thermocouple. The main advantage of an RTD is its accuracy, and that ordinary
copper wire is used as an extension lead wire. Resistance of the lead wire can affect
the accuracy of the reading. Calibration data is ITS90. Other measurements or tables
such as IPTS68, should be specifically requested. 1/4 inch (6.35 mm) O. D. RTDs are
usually used as they have a thicker wall than smaller O. D. tubes which makes them
stronger, and, they tend to be better in vibration environments.

Note: ITS90 varies from IPTS68 by about:

           +0.01 º C at - 40 º C
             0.00 º C at      0 º C
            -0.06 º C at   420 º C
